This figure shows VP-2064.
1. Channel power indicators [pOwER]
only the indicator for the input module-mounted
channel lights green when the power is supplied.
• Off: VP-200VX not installed
• Lights green: In-use status
• Lights red: Standby status or DC fuse blowout
2. Overheat indicator [OvERhEAT]
If the internals of the power amplifier overheat, this
indicator lights yellow and the power amplifier's
operation is stopped.
3. Functional Earth Terminal
Hum noise may be generated when external
equipment is connected to the unit. connecting
this terminal to the functional earth terminal of the
external equipment may reduce the hum noise.
Note: this terminal is not for protective earth.
4. DC power input terminal [DC pOwER IN]
connects to the VX-2000DS or VX-3000DS
Emergency Power Supply's Dc PoWEr out
terminal.
5. Output terminals [pA OUT (Sp LINE)]
Connect to the amplifier input terminal of the SX-
2100Ao Audio output unit.
the speaker line output voltage can be changed
with an internal modification.
For the modification procedure, see p. 89 .
6. Module Slots
Insert the VP-200VX Power Amplifier Input
modules into these slots.
four different configurations of power amplifiers can be used in the SX-2000 system: 60 W x 4 channels, 120
W x 2 channels, 240 W x1 channel, and 420 W x 1 channel versions. mount a VP-200VX Power Amplifier Input
module for each channel used.

1. Input connector [pA LINK]
this rJ45 connector connects to the SX-2100Ao's PA lINK
(ZoNE 1 – 8, StANDBy) connector. output audio signals are
transmitted to the power amplifier, and the power amplifier's
audio monitor signals are returned to the module.
It is also possible to retrieve data regarding power amplifier
overheating status and blown Dc fuses.
Insert this module into the VP-2000 series Power Amplifier's Input module slot when in use.
